JACOB FISHMAN, OF NEW YORK, N. Y.

SAFETY m'svrcn FOR WINDOWS.

T 0 all whom it may concern:

Be it known that I, JACOB FISHMAN, a subject of the Czar of Russia,residing at New York city, Manhattan borough, county and State of NewYork, have invented certain new and useful Improvements in SafetyDevices for Windows, of which the following is a clear, full, and exactdescription.

This invention relates to safety devices for windows, the object beingto rovide a device that is adapted for attac nnent to the window sashes,the said device being also adapted to limit the vertical movement of thesaid windows. In other words, my improved safety device is for thepurpose of preventing either the lower or upper sash from being openedmore than a predetermined distance, the said distance being controlledby the adjustable member of the device.

A detailed description of my improved device will not be given, andfinally claimed, reference being had to the accompanying drawing,wherein- Figure 1 illustrates a face view of a window casing providedwith an n per and lower sash, the said sashes being 0 osed and providedwith my improved safety device;

ig. 2 is a similar view, the upper sash being shown as lowered; Fig. 3is an enlarged vertical sectional view, taken through the sashes andpanes carried thereby, that part or member of my device which is carriedby the lower sash being shown in section, and the part or member whichis carried by the upper sash being shown in elevation; Fig. 4 is avertical sectional view of the lower part of the upper member of mydevice, the adjustable stop, carried thereby, being shown in elevation;Fig. 5 is a erspective view of an adjustably mounted firacket adapted tosupport the upper member of myimproved safety device; and Fig. 6 is asectional plan view of another form of the slidably connected members.

Referring now to the drawing, the numeral 1 indicates the upper sash andpane of a window, while 2 indicates the lower sash and pane thereof. Tothe top of the lower sash 2, preferably adjacent one side, I pivotallysecure, by means of a bracket 3, a tubular To the upper sash 1 Ipivotally secure, by means of a bracket 5, an upper tubular member 6,the lower end of said upper tubular member being provided with anadjustable stop 7. The stop 7 is threaded Specification of LettersPatent.

into the lower end of the upper tubular member for the purpose ofregulating or limiting the vertical movement of either the upper orlower sashes. A further object of the adjustable stop 7. is to permitthe lower and upper tubular members t and 6 respectively, to separatewhen the sashes are completely closed. The stop 7 will extend far enoughbeyond the lower end of the upper member 6, when the upper sash isclosed, to enter the lower tubular member 4, whereby the said tubularmembers are kept in alinement, as shown in Fig. 1. The object ofadapting the said tubular members l and 6 for separation is to exposeenough of the stop 7 to permit the said stop to be grasped by the handand screwed into the member 6 far enough to clear the lower tubularmember 4, whereby the said tubular members can be swung outwardly ontheir respective brackets. The upper or lower sash can, when the saidtubular members are swung outwardly, be moved to any extent within thelimits of the window frame.

As can be seen in Fig. 3, the upper member 6 is adapted to slidably fitwithin the lower tubular member l, and when the upper sash is moveddownwardly the stop 7 will contact the bottom of the said lower tubularmember and prevent further movement on the part of the upper sash. Theopening between the upper sash and window frame can be varied byscrewing the stop 7 inwardly or outwardly. To adapt the upper sash 1 forstill further adjustment, I secure to the said sash a channeled sliderest 8, which is provided with a slot 9. Upon the slide rest 8 Islidably or adjustably secure, by means of a gib 10, (which is adaptedfor longitudinal movement in the channel 1 1 of the slide rest 8) abracket 12. The gib 10 carries a nib 13, with which a nut 14 engages. Byunscrewing the nut 14 the bracket 12 can be moved up or down, wherebythe upper member 6, of the device, will be moved correspondingly. T heabove described adjustable bracket enables me to control the movement ofthe sashes to a considerable extent. It will of course be understoodthat the upper member 6 may be solid instead of tubular, and that hollowsquare members 15 and 16, shown in Fig. 6, can be used instead of thetubular members 4 and 6.

Having now described my invention, what I claim and desire to secure byLetters Patent is:

A safety device for windows, comprising a Ill;

tubular member pivotally mounted oni the lower Window sash, a tubularmemberfp ivob ally mounted on the upper window sash adapted to slidablyengage the tubu1armem- .5 ber first named, said upper sash tubularmember being adapted to disengagethe.

lower sash tubular member, when saict'sashes are closed, and anadjustable stop carried by the lower end of the upper sash tubularmember, adapted for removal therefrom. Signed at New York city, N. Y.,
